The methods for controlling the migrations of sand from unconsolidated formations are sometimes (arbitrarily) divided into 2 classifications. Mechanical includes screens (or liners), gravel packs, and combinations of the 2. Chemical or consolidation encompasses locking or agglomerating the formation in place by means of resins with acceptable loss of permeability. Packing and consolidating simultaneously is not being done in some wells. Formation sand may be mechanically controlled by a screen or a combination of a screen and gravel or sand pack or a pack alone in some cases. The screen, if used, should span the entire productive interval. The term gravel pack is not really appropriate in most cases since a closely graded sand is used. Some operators arbitrarily select gravel or near-gravel without regard to the size of the formation sand. The most commonly used techniques for applying screens and/or packs are described. Combination packing and consolidation has been successfully applied and commercially available for about 4 yr. There are at least 3 processes or variations available. These are identified and described by trade names and with the companies supplying the service.
